有没有办法压缩从php（服务器）发送的数据，然后使用javascript（客户端）解压缩数据？

Is there a way to compress data sent from php (server) and then uncompress the data using javascript (client)?

感谢您

我必须同意@ Domenic的答案。 @ Nishchay Sharma is off off。

I have to agree with @Domenic's answer here. @Nishchay Sharma is way off.

我要添加的唯一的事情是，如果你想在每个脚本基础上这样做，而不是配置整个服务器压缩一切，通过使用PHP的gzencode（）函数和头调用来完成你的目标是微不足道的：

The only thing I'll add is if you want to do this on a per-script basis rather than configuring your entire server to compress everything, it's trivial to accomplish your goal by using PHP's gzencode() function coupled with a header call:

http://www.php.net/manual/en/function.gzencode.php

例如，假设您通过对PHP页面的Ajax调用来检索大量数据。你可以配置PHP页面使用gzencode如下：

For instance, let's say you are retrieving a huge set of data via an Ajax call to a PHP page. You could configure the PHP page to use gzencode as follows:

<?php
$someBigString = gzencode('blahblah...blah');

header("Content-type: text/javascript");
header('Content-Encoding: gzip'); 

echo $someBigString;  
?>

（这过于简化了，当然，但我保持简单。）

(This is overly simplified, of course, but I'm keeping it simple.)

您的JS Ajax调用将拉下数据，查看gzip头，并自动解压缩。我个人使用这种技术用于Google地图的非常大的地理坐标数据集，在解压缩时可以有多个兆字节的大小。这不容易！

Your JS Ajax call will pull the data down, see the gzip header, and decompress it automagically. I personally use this technique for very large geo-coordinate data sets for Google Maps that can be many megabytes in size when uncompressed. It couldn't be easier!
